• Do not open or service a pressurized A/C system without first properly evacuating it using recovery equipment.
• Wear safety glasses and gloves when handling refrigerants, oils, or compressor components.
• Never allow refrigerant to come into contact with your skin or eyes — it can cause severe frostbite or chemical burns.
• Use only EPA-certified refrigerant recovery and recycling equipment.
• Ensure you are working in a well-ventilated area to avoid inhalation of refrigerant gases.
• Do not use compressed air to test or clean A/C components — mixing air and refrigerant is explosive under pressure.
• Verify that the replacement compressor uses the correct oil type and amount as specified by the vehicle manufacturer.
• Do not mix refrigerant types (e.g., R-134a with R-1234yf) — this can cause system damage or contamination.

• If you’re unsure about any part of the installation or servicing process, consult a professional technician.
